Propyl propanoate may be made in three stages, with propanenitrile as the sole organic starting material. During step 1, the nitrile is changed into compound X. During step 2, compound X is changed into compound Y. During step 3, compound Y is reacted with additional compound X to produce propyl propanoate. $\text{CH}_3\text{CH}_2\text{CN} \rightarrow X \rightarrow Y \rightarrow \text{CH}_3\text{CH}_2\text{CO}_2\text{CH}_2\text{CH}_2\text{CH}_3$ Which reagents would be suitable for step 1 and step 2?
- Astep 1: HCl(aq); step 2: conc. $\text{H}_2\text{SO}_4$
- Bstep 1: HCl(aq); step 2: $\text{LiAlH}_4$
- Cstep 1: NaOH(aq); step 2: conc. $\text{H}_2\text{SO}_4$
- Dstep 1: NaOH(aq); step 2: $\text{NaBH}_4$
